1. Data Files Structure LAT Volvo/LAT Lab Is there an additional level of data necessary (Volvo proposal)?

2. Data Submission Progress I  February 2003  LD: EMPA  HD: VTT, AVL, TUG  First release of test data  We received nothing  March 2003  LD: Shell  HD: Volvo, TUG, MTC  Second release of test data  We received nothing  April 2003  First release of Consolidated Test Data  LD: MTC, IFP, LAT  Third release of test data  We received HD from VTT, AVL  May 2003  Second release of Consolidated Data (May, 9)  LD: Inrets  HD: Volvo (addit.)  Final release of test data (wk 21 – May 23)  End of May: Cut-off of data submission

3. Data Submission Progress II  However things are not as bad as the previous slide indicated. We are in contact with most of the partners and we know what the situation is  Status of progress  AVL: already sent 1 st release  VTT: already sent 1 st release  TUG: in progress: work on files  VOLVO: done w. measurements, work on files  LAT: Still measuring and producing files  EMPA: done w. measurements, work on files  Shell: diesels done, complete gas. by end of May, working with files  MTC: work on files?  IFP: ?  INRETS, AEAT

4. Steps Ahead  Individual labs:  Send any data by May, 9.  FINAL DATE FOR SUBMISSION REMAINS MAY, 30. Drafts of lab reports should be ready by May, 30.  Co-ordinator:  Prepare database (1 st consolidated data version) and circulate it immediately (May, 12).

5. Consolidated Data Evaluation  Focal points (Concawe, Volvo, TUT, EMPA) receive:  1st consolidated version (CV) May, 12  2nd CV June, 6  Key elements of evaluation: 1. Confirmation of adequacy of QA/QC (Concawe, Volvo). Wet/dry branch comparisons (TUT). 2. Identification of outliers (Concawe, Volvo) 3. Statistical evaluation (2 nd CV) 4. Follow-up based on 1, 2 (LAT)  Indicative evaluation by May, 30 (1 st CV). Final evaluation by June, 30 (2 nd CV).  Definition of standardised representation of consolidated data for D11-D14 by May, 30. (LWA)

6. Final Report Structure  Introduction  Health effects  One Chapter per Deliverable  D2: Instruments  D3: Sampling  D7: Road-side measurements  D8: Non-exhaust  D11: Current vehicles  D13: “Anticipated” technologies  D12: Off-cycle  D14: Fuel effects  Validation of measurements (Ford)  D15: Relevance of current PM emission standards and further aspects  Summary & Conclusions 1 st draft by July 15 latest to LWA/LAT

7. Which are the main (unanswered) relevant questions in the scientific community?  Sampling  CVS  MDSs  Practices / Recommendations  PMP-Relevant Questions  Where do we go from mass  How much can mass measurement be improved  Which are alternative particle properties  Number  Size  Surface  Chemistry  Relevance of nuclei mode  Is it necessary to measure  Can it be measured accurately with repeatability  Is it an artefact with no relevance to the atmosphere
